Q2 2023 | Stockholder letter 2 To Our Fellow Stockholders It is an exciting time at TrueCar! It is a time of change and a time of focus. We have turned the ship and we are laser focused on growing the business. In Q2, we achieved quarter over quarter revenue growth, significantly improved our bottom line and have visibility to Q3 year over year revenue growth, followed by double digit revenue growth and adjusted EBITDA1 profitability in Q4 2023. In mid-June, we streamlined our organization and eliminated 102 positions, or 24% of our headcount. Although these are always difficult decisions, it was an important step to be a nimbler company and more focused company. As part of this decision, we also announced a leadership transition, with the appointment of Jantoon Reigersman as President and Chief Executive Officer. We have so many diamonds in the rough that are ready to shine. We are excited to polish those together over the many quarters to come and transform this business for long term success. As an example, did you know that more than 50% of the nationwide supply of electric vehicles, excluding Tesla, is in stock and available on TrueCar? We have a unique opportunity to disrupt our market and redefine our value proposition to both our customers and dealers. We are excited to bring you along on this journey with us and we will elaborate more on this in the coming quarters, starting with the cohort launches we expect to occur through the end of the year. Our plan to grow revenue continues to take shape as we are rebuilding our core business with our dealers. During the second quarter, and despite lower total dealer count quarter over quarter, we increased the number of franchise dealers by 191 while also growing our revenue per dealer. The lower total count was primarily due to the continuing challenging conditions in the used vehicle market, resulting in a loss of 382 smaller independent dealers. We continue to strengthen our sales force and expect revenue per dealer to continue to increase, adding higher net monthly recurring revenue. Though the overall market environment remains mixed, we continue to anticipate double-digit revenue growth compared to Q4 2022 and breakeven or positive adjusted EBITDA in the fourth quarter as we remain diligent on our expenses while investing in areas that will help us achieve our key priorities for 2023. Our improved adjusted EBITDA results for Q2 2023 reflect our commitment to achieve this goal. As mentioned in our last stockholder letter, we have started to develop a more personalized, dynamic experience tailored to different consumer and dealer profiles. This personalized experience will be based on a consumer’s buying power and preferences, which include: (1) tailoring the shopping experience based on what the consumer can afford; (2) delivering personalized recommendations; and (3) providing dynamically enabled features to optimize consumer/vehicle matching. With limited resources and a greater emphasis on focus, we have selected three personalized experiences or cohorts for rollout 1 Adjusted EBITDA is a non-GAAP financial measure. Refer to its definition set forth below. We are unable to provide a reconciliation of forward-looking Adjusted EBITDA to GAAP net loss, the most comparable financial measure calculated and presented in accordance with GAAP, without unreasonable effort because of the uncertainty and potential variability in amount and timing of stock-based compensation, lease exit costs and impairment of right-of-use assets, which are reconciling items between GAAP net loss and Adjusted EBITDA and could significantly impact GAAP results.

Q2 2023 | Stockholder letter 3 throughout the remainder of this calendar year: (1) Economic Buyers, typically budget-conscious consumers who may have low credit scores or limited credit histories who often shop for used vehicles; (2) Convenience Buyers, who tend to have higher credit scores and who typically shop for new or certified pre-owned vehicles or lease vehicles; and (3) Electric Vehicle (EV) Buyers, who are exploring and comparing different electric vehicles and evaluating the benefits of new or used EV options. We expect these personalized journeys to not only improve conversion of our healthy top of funnel traffic, but to also increase the volume of transactions. In closing, we would like to thank our team members for their passion, focus and support as we continue this exciting journey to make online car buying trustworthy, easy and accessible to everyone. Humble, nimble and focused. Jantoon Reigersman President and Chief Executive Officer Teresa Luong Chief Financial Officer

Q2 2023 | Stockholder letter 4 Market Environment During the second quarter, new vehicle inventory declined slightly from the 1.8 million units seen in March 2023 before rising back to 1.9 million units at the end of June. Affordability remains a concern for many consumers as interest rates remain high and vehicle markups are significantly higher than pre-pandemic periods, increasing the overall cost of leasing or financing vehicles. Domestic brands continue to garner the largest share of inventory gains. New vehicle inventory rose to 1.9 million units in June 2023, up 62.1% or approximately 711 thousand units from June 2022. On a sequential basis, new vehicle inventory increased by a modest 3.2% or 58 thousand units from March 2023. While this progress has improved significantly year over year, current year inventory improvement has slowed and is far below pre-pandemic levels of 3.5 million to 4 million units. Domestic OEM brands continue to garner a larger share of the gains. Source: Motor Intelligence New Vehicle Inventory (Industry)

Q2 2023 | Stockholder letter 5 The disparity across brands is also evident in days’ supply of inventory, which for domestic brands stood at 49 days on average in June 2023, above the industry average of 35 days. Days’ supply of inventory for European brands was 27 days, while Japanese and Korean brands combined were at 22 days.

Q2 2023 | Stockholder letter 6 New inventory gains in 2023 are also skewed toward higher price ranges with 62% of new vehicle inventory consisting of vehicles priced above $40 thousand compared to 34% from 2019. This shift is consistent with the increase in average list price that we’ve seen at $52 thousand in June 2023. New Vehicle Inventory Share by List Price Source: Truecar

Q2 2023 | Stockholder letter 7 Vehicle sales trends. Industrywide new vehicle sales were approximately 4.1 million units during the second quarter of 2023, based on data from Motor Intelligence, compared to 3.6 million unit sales in the first quarter of 2023 and 16.8% above the levels seen in the second quarter of 2022. Monthly new vehicle sales were approximately 1.4 million units for June 2023, flat to March 2023 and trending closer to the 1.5 million units seen in pre-pandemic levels in June 2019.

Q2 2023 | Stockholder letter 8 The seasonally adjusted annual rate (SAAR) for the second quarter rose to 15.7 million units with April peaking at approximately 16.1 million units followed by a decline in May before inching back up in June. Source: U.S. Bureau of Economic Analysis Light Vehicle Seasonally Adjusted Annual Rate (SAAR) On average, the supply of new vehicles has continued to improve slightly for the industry, however, as we observed earlier, this progress is still not widespread with gains mainly seen for domestic brands while shortages continued to persist for certain brands like Toyota, Hyundai, Kia and Subaru (as of June 2023).

Q2 2023 | Stockholder letter 9 Vehicle price trends. Across the industry, approximately 41% of new vehicles sold above their Manufacturer’s Suggested Retail Price (MSRP) in June 2023, relatively consistent with March 2023, while reflecting the continued downward trend from 66.8% in June 2022. OEM incentives for new vehicles increased 83.6% on a year-over-year basis to $2,038 in June 2023. June incentives were up 32% from March 2023. Although from a percentage basis, it may appear significant, they remain well below the average incentive of $3,400 to $4,300 seen in pre-inventory shortage and pre-pandemic periods. While incentives are starting to increase, these increases are driven mainly by luxury imports, Ford and Jeep. The top 10 selling brands all increased incentives in June 2023 compared to the previous year, in contrast to March 2023 where six of the same top 10 brands reduced incentives compared to the previous year.

Q2 2023 | Stockholder letter 10 In a broader review of vehicle price inflation, the Consumer Price Index (CPI, not seasonally adjusted) for new vehicles rose 4.1% year over year and increased by 0.1% month over month in June 2023, both metrics reflecting increased pricing but at a much slower pace than for the same periods in 2022. The CPI for used cars and trucks declined by 5.2% year over year in June but increased by 1.2% from May. The month over month rise in June is the fourth straight consecutive increase this year and likely reflects the tightening supply for used vehicles as consumers turn to used vehicles looking for better affordability.

Q2 2023 | Stockholder letter 11 Affordability remains a concern. The average list price for a new vehicle on TrueCar.com was approximately $52 thousand in June 2023, up 8.0% from a year ago and up 3.6% from March 2023. For now, the combination of still-high prices, rising interest rates and modest OEM incentives mean that monthly payments for new cars will likely remain elevated. For the remainder of the year, we expect OEM incentives to increase as days’ supply grows. However, we expect incentive offers to vary by brand and/or model. Little has changed in these past three months for consumers as the average down payment on a new car loan declined by about 1% from Q1 2023, pacing a similar decline in the amount financed over the same period. The average monthly payment for a new vehicle grew about 1% from Q1 2023 and 10.9% year over year to $761 in Q2 2023. Average interest rates for new car loans were relatively flat from Q1 2023 at 7.1% vs 5.1% in Q2 2022. New and Used Vehicle Financing Trends Source: Truecar The average list price for a used vehicle on the TrueCar platform was approximately $32 thousand in June 2023, down from approximately $33 thousand a year ago. Interest rates for used vehicle loans declined to 10.9% in June 2023, from 11.0% in March 2023 and rose from 8.3% in June 2022. The average monthly payment for a used vehicle was $595 in June 2023, up 3.2% year over year and from $583 in March 2023. According to the latest automotive finance market update by Experian2, the share of new and used vehicle loan and lease transactions for subprime and deep subprime buyers continues to decline to 16.1% in Q1 2023 from their updated numbers of 17.7% in 2022 and 23.8% in 2019 while super prime and prime buyers comprised 66.3% in Q1 2023, up from 59.1% in 2019. 2 Experian: State of the Automotive Finance Market Q1 2023

Q2 2023 | Stockholder letter 12 Company Updates In designing the vehicle shopping experience to be flexible based on consumer needs and preferences, we are focusing on three key cohorts to enable personalized experiences in the near term: (1) Economic Buyers; (2) Convenience Buyers; and (3) EV Buyers. Over time, the type and amount of cohorts will further expand. For now, focus and transactions are key. In addition to tailoring personalized experiences for these cohorts, we have also started to build a unified flow or a single storefront experience. We envision this unified flow will provide a single storefront for consumers to step into as they begin their car-buying journey while allowing off-ramps for those consumers who wish to finish their purchase at a dealership. We are in the process of unifying the vehicle details page (VDP), which will ensure a consistent user interface across all vehicles, allowing for easier navigation and comparability across vehicles. We expect the launch of the unified VDP redesign to be completed before the end of September 2023. We anticipate that this unified flow will allow us to offer in the future a digital flow with offramps for a traditional lead, a super lead or for a completed transaction. This is an important stepping stone for a seamless consumer experience. This is no longer a traditional lead flow versus TrueCar+, rather all consumers will walk a single digital path with the option to go “off line” at various decision points. It will be our task over time to make the digital alternative so attractive and compelling that more and more people seek to complete their purchase online in the future. Economic Buyers. Per Experian, one-third of Americans are estimated to have subprime or deep subprime credit scores. For consumers who have started a credit application through TrueCar+ in these past six months, approximately half of these consumers have subprime or deep subprime credit scores. These consumers tend to have limited options for financing and struggle to know if they will be approved before deciding on a vehicle and having a hard credit pull. This has led to many frustrating experiences as many of these consumers fail to get financing approval on their selected vehicles. These are also customers who often encounter unsatisfactory dealer experiences and as a result seek an online solution that is fair and treats them with dignity. TrueCar’s goal for the economic cohort is to empower credit-challenged consumers by curating vehicle selection for this cohort based on their purchasing power prior to a hard pull credit application and by providing pre-approved financing offers with feasible down payments and monthly payments. We believe that presenting these vehicles upfront will align consumer expectations with the realities of their purchasing power, avoid credit denials that will exacerbate their credit score and expedite the car-buying process for this audience. By changing the order of operations, our goal is for consumers to be empowered to shop for and know the vehicles for which they are pre-approved, including the financing terms. Note that we do not intend to provide pre-qualification to merely assess someone’s credit profile, rather an actual pre-financing and de-facto pre-approval. We anticipate that dealers will also benefit from this new experience as dealers will have access to a large audience with an opportunity for high sales volume, acceleration in inventory turnover, and a more efficient process as the financing details will already have been resolved online, while maintaining attractive F&I incentives for the dealers (unlike current market offerings).

Q2 2023 | Stockholder letter 13 In April 2023, and as disclosed in our last stockholder letter, we released a buying power calculator that allows consumers to find their estimated buying power based on their maximum desired down payment, desired monthly payment and user-volunteered credit score. Since the release, approximately 5,000 consumers per day have interacted with this tool, and approximately 30% are self-identifying as having either poor or fair credit scores. This audience is the focus of our new economic cohort experience flow, which we are seeking to launch in September 2023. Convenience Buyers. We define this cohort as consumers with a high credit score (750 or above) and who can be more selective in the car-buying process and want the overall experience to be easy, fast and streamlined. Our vision is to serve these high credit score shoppers in a compelling way by optimizing their dealer and lender experiences. Within our platform, we envision that the first step of this cohort’s journey will be the ability to walk through a simple, guided flow that matches their preferences to vehicles in as few steps as possible. Our platform will offer these consumers a vast dealer inventory and comparability between makes, models and payment options, as well as transactable pricing and fee transparency. Once a specific vehicle is selected, these shoppers will be offered competitive rates from a limited set of reputable lenders targeted at these credit profiles, allowing for ease of comparability and convenience. This cohort will also seek to add accessories and protection products in an easy convenient way, which is something we have already tested and proven in our current flow with what we believe is the most comprehensive nationwide accessories selection of any online automotive marketplace. We expect that our dealer network will benefit from this cohort experience as they’ll have access to a large, high credit worthy consumer base, high sales volume opportunity, attractive margin per vehicle that can include accessories and protection products, intact financing fees, access to nationwide online sales without any of the infrastructure costs, and acceleration in inventory turnover. We are targeting to release the convenience cohort experience in October 2023. EV Buyers. As the name implies, this consumer base is primarily interested in electric vehicles. We are striving to provide an experience that includes: (1) easy discovery; (2) comparability of features like battery life and range across EVs; (3) comparability between EVs and internal combustion engine (ICE) vehicles; and (4) all the features and functionalities provided to the convenience buyers. With more than 50% of the nationwide supply of EVs, excluding Tesla, in stock and available on TrueCar, we offer these EV buyers both convenience and selection. For our dealer network, we offer a unique EV focused sales channel and all the benefits of those dealers within the convenience buyers cohort. Our goal is to launch the EV experience in November 2023. To further underscore our strength in EV, in Q2 2023, we activated two Mercedes-Benz (MBUSA) incentive offers on Sam’s Club and American Express. As part of this promotion, we worked with MBUSA to place vehicles within several Sam’s Club locations to raise further awareness and consideration of their vehicles, with a focus on their EVs. Of the total MBUSA sales that were driven by our affinity partners, over 50% of these sales were EVs. The response to this promotion to date has exceeded MBUSA’s and our expectations and speaks to the power of our Affinity Partner network.
